nemesis isnt that hard...but it gets annoyin tryin to beat him over and over and over for one shield or somethin DAMN to defeat him just use quick hit wit ne of ur 99,999 characters. then summon an aion right b4 nemesis attacks. attack wit ur aion and do this over and over. if 2 of ur chars do 99,999 dmg then u might have to use all ur aions. try to have a third member do 99.999 dmg it helps alot LaTeRzZ
IF U GOT NEMORE QS AIM ME AT SUPRA397

Nemesis' most common move seems to be to simply attack one character. Given his 255 strength, this is generally capable of doing in the neighborhood of 99,999 damage, but it may be survivable with a Break HP Limit character with Protect using Sentinel. His next choice appears to be Ethereal Cannon, a special attack which also targets one character for 99,999 damage. His rarer attacks, Ultra Spark and Annihilation, are both capable of hitting ALL characters for 99,999 damage.

I should note that I've never seen Nemesis use an attack that hits all twice in a row, and it may be that he never does, but I haven't fought him nearly enough yet to be certain of that.

The name of Nemesis' strongest attack is Armageddon, not Annihiliation.

Also note that all of Nemesis' attacks other than Armageddon will deal no more than ~10,000 damage (and frequently less) to an Aeon with very high (230+) defense and magic defense if the Aeon uses Shield, and this damage can be further lowered by Protect/Shell. However, Armageddon still hits for 99,999.

Actually it's pretty easy to defeat it. Use Wakka's overdrive "Attack Reels" a couple of times will do. (Damage 70000~99999 each hit, maximum 12 hits) Make sure you have "one mp cost" and cast "auto-life" on every character. And if you have extra moves, just attack him directly because he won't counter you.

i maxes out every stat with every character, and it still took more then an hour. i did attack reels and tidus's special like 30 times. and he can do more then 10000 dmg. he hit me with a few 99999. which makes me believe some of u never realy beat him.

Couldn't you just pay yojimbo enough gil for a zanmato? since you can get about 100,000 gil for defeating a mimic in the omega ruins and assuming your characters are strong enough to defeat it in one go then would this not be a quicker way? (I have yet to try this myself)

to beat nemesis you need to hit him approximately 100 times for 99,999 damage any way you like as long as you do 99,999 i personaly ue wakka lu lu and tidus since all of there overdrive can do awesome damage multiple times ofcourse when armgeddon comes you need to swich to yuna and summon an aeon or sqwich to rikku and use auto life.(ypu can cast auto life yourself but it costs alot of mp)

umm take a look at some videos on youtube of nemesis i saw a guy solo nemesis in 30 mins useing auron no overdrives so ummm clearly you didnt max out every stat tidus can solo nemesis in about 10 mins if you did max out every stat then your just realy bad.

No his normal attack couldnt even do 6000 damage to me. and his eatheral cannon did only around 10000. His ultra spark did around 30000 but i would always die anyway as i don not believe in BHL. I think you over exaggerated the fight a little too much.

Are you kidding me?? It took you that long with max stats? My stats arent even maxed yet (theyre close bu im too lazy) and I beat him less than 10 minutes. The key is to use Hyper Mighty Guard. You must have a pattern somewhere.

With my HP/MP maxed, Strenght, Defense, Magic Defense, Agility and Accuracy maxed, Nemesis took about 10 minutes. Wakka's Overdrive "Attack Reels" (as stated above) deals 12 hits, though mine were only for 70-80K, is probably the best way (less Zanmato) to defeat Nemesis. Quick hits in between using Entrust to give other character's Overdrive bar to Wakka and continue going back and forth between that method and Quick Hit. I also start out the battle by using Rikku's Mix Overdrive to cast "Hyper Mighty G". It casts Protect/Shell/Regen/Haste/Auto-Life on the party and is a great way to start the battle.

Other than getting hp sphere from ironclaq at monster arena, is there any other easier way to get hp sphere??
If keeping killing ironclaq, it is wasting too many time as it's hp is high n everytime counter!!! Any suggestion??

8B@LL's tactic works like a charm, i won Nemesis without using a single overdrive and from the style i used to beat him,
all you actually need is
-255 strength
-255 agility
-Quick Hit (Ability)
-Haste on team

My Team: Yuna, Tidus, Rikku
Strategy: Quick Hit spam, summon aeon when boss is going to attack, aeon dies, team returns and quick hit spam again, repeat until he dies, at the end of the match, my characters didn't take a single damage and i had Magus Sisters and Yojimbo left.
